AH180N MICROPOWER OMNIPOLAR HALL-EFFECT SWITCH Description The AH180N is a high sensitivity, micro power Omnipolar Hall Effect switch IC designed for portable and battery powered equipment such as cellular phones, PDA’ s and portable PC’ s. Based on two sensitive Hall Effect plates and a chopper stabilized architecture the AH180N provides a reliable solution over the whole operating range. To support portable and battery powered equipment the design has been optimized to operate over the supply range of 2.5V to 5.5V and consumes only 24µA with a supply of 3V. The single open drain output can switched on with either a North or South pole of sufficient strength. When the magnetic flux density (B) is larger than operate point (Bop) the output is switched on (pulled low).
